It was especially designed for placing it in the areas without any supply voltage and its ideal placement is on main pipelines, sewerage or various sewage conduits. The flow meter excels in high accuracy within the entire flow range.Prior to every measurement, automatic diagnosis of all functions and components that are necessary for proper admeasurement takes place. Based on the results, the meter is able to identify if the pipeline is empty and it cancels the entire measurement and/or conversely, it will evaluate the flow direction and include the results in corresponding summation registries.Battery charging is directly dependent on the measurement period selected and on the outputs used; in case of a 10-sec period, the service life is 6 years min.MAIN ADVANTAGES• powered by internal lithium • batteryoptional external power supply• module for GMS data transmissiondata archival on micro SD card• nearly maintenance-free operation• 350° swivel display for comfortable reading• simple and trouble-free installation and operation• no pressure lossesDN 10 - DN 400PN 10 - PN 40
